Special slow-released fertilizer for cotton

Abstract

A special slow-released fertilizer for cotton comprises the following raw materials in parts by weight: 15-25 parts of urea, 6-8 parts of a nitrogenous fertilizer, 6-8 parts of phosphatic fertilizer, 3-5 parts of cortex meliae powder, 4-6 parts of decoction dreg ashes, 7-9 parts of potassic fertilizer, 5-7 parts of plant ash, 3-5 parts of sepiolite, 2-4 parts of monoammonium phosphate, 5-15 parts of quick lime, 4-6 parts of copper sulfate and 20-30 parts of water. According to the special slow-released fertilizer for the cotton, provided by the invention, various nutritional ingredients can be slowly released, nutrient loss is avoided, single fertilization without topdressing is achieved, environmental pollution is avoided, and the cotton yield is further increased.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a special slow-release fertilizer for cotton. Background technique [0002] Cotton is the most important economic crop in northern my country. To achieve high yield, cotton must have sufficient fertilizer in each growth period. However, the existing cotton special fertilizer cannot be released slowly, resulting in uneven release of cotton during the growth period, which cannot meet the needs of cotton growth. need, and the existing cotton fertilizer is lost in a large amount after application, which is wasteful on the one hand, and also causes environmental pollution on the other hand. In order to solve the above-mentioned drawbacks, the present invention has developed a special slow-release fertilizer for cotton. , potassium and various trace elements are reasonably configured and can be released slowly, so it is helpful for cotton growth, cotton yield is increased by 20-25...

Problems solved by technology

[0002] Cotton is the most important economic crop in northern my country. In order to achieve high yield of cotton, there must be sufficient fertilizer in each growth period. However, the existing cotton special fertilizer cannot be released slowly, resulting in uneven fertility release during the cotton growth period, which cannot meet the needs of cotton growth. In addition, after the existing cotton fertilizer is used, it will be lost in large quantities. On the one hand, it will be wasted, and on the other hand, it will also cause environmental pollution. , Potassium and various trace elements are properly configured and can be released slowly, so it is helpful for the growth of cotton, and the cotton yield is increased by 20-25%. At the same time, the pests and diseases during the cotton growth period are reduced
